快速入门

引入maven依赖

<!-- 引入elastic-job-cloud执行器模块 --> 
<dependency> 
    <groupId>io.elasticjob</groupId> 
    <artifactId>elastic-job-cloud-executor</artifactId> 
    <version>${latest.release.version}</version> 
</dependency> 

作业开发

public class MyElasticJob implements SimpleJob { 

    @Override 
    public void execute(ShardingContext context) { 
        switch (context.getShardingItem()) { 
            case 0: 
                // do something by sharding item 0 
                break; 
            case 1: 
                // do something by sharding item 1 
                break; 
            case 2: 
                // do something by sharding item 2 
                break; 
            // case n: ... 
        } 
    } 
} 

Java启动方式

需定义Main方法并调用JobBootstrap.execute()，例子如下：

public class JobDemo { 

    public static void main(final String[] args) { 
        JobBootstrap.execute(); 
    } 
} 

打包作业

tar-cvf yourJobs.tar.gz yourJobs

发布APP

curl -l -H "Content-type: application/json" -X POST -d '{"appName":"foo_app","appURL":"http://app_host:8080/yourJobs.tar.gz","cpuCount":0.1,"memoryMB":64.0,"bootstrapScript":"bin/start.sh","appCacheEnable":true,"eventTraceSamplingCount":0}' http://elastic_job_cloud_host:8899/api/app 

发布作业

curl -l -H "Content-type: application/json" -X POST -d '{"jobName":"foo_job","appName":"foo_app","jobClass":"yourJobClass","jobType":"SIMPLE","jobExecutionType":"TRANSIENT","cron":"0/5 * * * * ?","shardingTotalCount":3,"cpuCount":0.1,"memoryMB":64.0}' http://elastic_job_cloud_host:8899/api/job/register
